For a long period of time back in high school, when a number of people thought I was going to become a computer engineer, I was interested in astrophysics more than anything. I took IBH Physics because I figured I’d at least have a good chance of getting into astrophysics if I did well in it. One of the unspoken reasons I chose University of Chicago was because it was one school that had a kick-ass physics program. While the economists would have you believe that Chicago is the home to the most economic Nobel prizes, that number is dwarfed by the number of physics Nobels. I actually tried sitting in on a couple of astrophysics classes in college, but I was kicked out once the Professors realized I wasn’t enrolled in the class (thank you so much, Prof. Truran, and Wayne).
Anyway, I ended up an economist. C’est la vie. Too late to change career paths.
But my interest in astrophysics has not suffered for this change in career path, between science fiction and borrowing telescopes and telescope time. However, one resource that I find stunning beyond belief is the pictures from ongoing missions page at NASA’s various control rooms. Some of my favourites:
- MER-A Spirit is exploring the Gusev Crater on Mars (see the panoramic camera shots for the best pictures).
- MER-B Opportunity is exploring Meridiani Planum on Mars (ditto).
- Cassini is orbiting Saturn and exploring the rings and moons of Saturn.
- New Horizons is flying faster than a speeding bullet to Pluto, via Jupiter.
- Messenger is whizzing to a rendezvous with Mercury.
You may notice that I’ve not bothered with the pictures from more remote sensing instruments. I used to be fascinated with the Hubble pictures, and still am, but a realization I’ve slowly come to is that no human will voyage beyond our solar system in my lifetime.
The average life expectancy at birth in India in the 1980s was just over 50 years; my family is long-lived by all comparisons – 80+ years is common. Even if I live that long, it means there are just some 60 years for me to voyage out into space. There’s no way I’m going to make it to the nearest known extrasolar system, ε Eridani, some 10.5 ly distant, without some combination of life extension, hibernation, inertial control and new sources of portable energy. Or the development of viable superluminal travel, which is even less likely. While I have immense faith in the ability of scientists to conquer such barriers, I do not have faith in the governments of humans to actually fund such development.
So rather than stare longingly at the stars, where humans will most likely never step even in two generations, better to look at our own solar system, where prolonged and sustained efforts will likely get us within a human lifetime. Thus, I look forward to moving to Mars when I retire.
I call dibs on Chryse Planitia.
